What is Betaflight CLI? CLI stands for command line interface, a configuration mode that gives users direct access to all the settings and parameters within the flight control firmware. CLI is a powerful tool, but can be daunting for less technical users. In this guide I will explain why and how to use CLI in Betaflight.

This tutorial explains how to calculate/estimate FPV range using the dB of your FPV equipment. Learning about this topics really help understand the capability and performance of FPV components, at least for me it was huge.

You often hear “higher gain antenna has longer range”, but don’t be fooled! Antennas doesn’t amplify radio signals, but rather just changes the radiation pattern, which is a trade-off between coverage and range. Antenna gain is a reflection of the maximum range you can get.

In this tutorial I will show you a few tips about soldering. Getting good at soldering takes some practice, but it’s going to be one of the most useful skills you’ll learn in this hobby. Your soldering quality also determines how reliable your mini quad and RC plane builds are going to be.

Many FPV devices require an SD card to work. In this guide I will recommend what micro SD cards to buy for GoPro cameras, Fatshark DVR, Taranis radio, as well as DJI drones. I will also explain the speed class letters on SD card labels.

Travelling with a drone includes some inherent inconveniences, but it’s really easier than it seems with a little preparation. Here are some basic rules to follow on how to travel with mini quad and LiPo batteries on an airplane.

BLHeli_32 ESC firmware allows you to play music with ESC by uploading custom startup tones to each ESC. You can now form a band with the 4 motors in your quadcopter and play a cool tune when powering up your drone.

This tutorial is written for complete beginners, which explains how to connect BLHeli_32 ESC’s to computer through “FC pass-through”, and how to use BLHeliSuite_32 to flash BLHeli32 firmware and configure ESC settings.

You can prolong the life of electronics in a quadcopter with waterproofing, the most common method is Conformal coating. It helps prevent components from moisture and chemical damage when flying in extreme conditions.

Not getting enough FPV range on 5.8GHz? This guide will explain the many aspects of using 1.2GHz – 1.3GHz video transmitters (VTX) and receivers (VRX) to get longer range. It will take you through selecting gears and some tips for optimal performance.
